    Abstract: An end effector for a robot having a threaded shaft; a motor coupled to the shaft and configured to rotate the shaft about its axis; a nut threaded onto the shaft; a feature for preventing the nut from rotating about the axis of the shaft; and an elongate member fixed at one end to the nut and extending from the nut in a direction parallel to the axis of the shaft. The end effector may further include a container for containing a fluid having an elongate body portion having an opening at one end; and a reciprocable plunger extending into an opposite end of the body portion. A second end of the elongate member may be coupled to the plunger.

    Abstract: An electric machine comprising: a) a first means for providing a first magneto motive force comprising a first set of magneto motive force space harmonics comprising odd and even harmonic subsets, each harmonic in said first set of magneto motive force space harmonics having a respective amplitude, wherein one of said odd or even subsets of said first set of magneto motive force space harmonics comprises a dominant working harmonic and the other of said odd or even subsets of said first set of magneto motive force space harmonics comprises a dominant undesirable harmonic; and b) a second means for providing a second magneto motive force comprising a second set of magneto motive force space harmonics comprising odd and even harmonic subsets, each harmonic of said second set of magneto motive force space harmonics having a respective amplitude, wherein one of said odd or even subset of said second set of magneto motive force space harmonics comprises a dominant working harmonic and the other of said odd or even subset of said second set of magneto motive force space harmonics comprises a dominant undesirable harmonic; wherein the net effect of said first and second means provides a resultant magneto motive force comprising a resultant set of magneto motive force space harmonics comprising odd and even harmonic subsets, each harmonic of said resultant set of magneto motive force space harmonics having a respective amplitude, wherein one of said odd or even subsets of said resultant set of magneto motive force space harmonics comprises a dominant working harmonic and the other of said odd or even subsets of said resultant set of magneto motive force space harmonics comprises a dominant undesirable harmonic, wherein the amplitude of the dominant undesirable harmonic of the resultant set of magneto motive force space harmonics is at least reduced relative to the amplitudes of the dominant undesirable harmonics of the first and second sets of harmonics.
